IMPROVED LOZENG-E AND CRACKER-MACHINE.

AThe Schedule referred to in these Letters Patent and making part of thename.

To all whom it may concern v Be it known that I, CHARLES A. OEHL, ofPortsmouth, Rockingham county, in the State ofNeW Hampshire, haveinvented a new and improved Lozenge and Cracker-Machine; and I herebydeclare the following to be a full and exact description thereof,reference being had to the accompanying drawings, forming part of thisspecification.

4The nature or essence of my invention consists in constructing acracker or lozengc-machine, so arranged that, bymeans of devices fullydescribed below, it shall receive and roll the dough, carry it forward acertain space, allow it to stop while the crackers are cnt out, theypassing through the cuttersa'nd then carry it on again, for anothersetto be cnt, and so on.

In the accompanying drawings- Figure l is an elevation of one side of amachine, with my improvements, and

Figure 2, a plan or top view.

In the above-mentioned drawings- A A are cast-iron side-frames,connected by the crossbars A1 A, which hold them a proper distanceapart, and.form a strong frame, to which most of the other parts of themachine are attached or connected, as shown in the drawings.

The maih shaft A2 is mounted in proper boxes on the sides A, and have acrank, pulley, or gear fastcned to it, to communicate motion from somemovingpower, to operate the machine.

The gear A3 is fastened to the shaft A2, and has two spaces, A" A4,without teeth, to let the rolling and conveying-apparatusV stop whilethe cutting apparatus forms the crackers or lozenges, as the case maybe.

The gear A3 turns the gear B and shaft B', which- 'carries the maincylinder', which is provided with ianges B2, to prevent the dough rolledbetween the main cylinder and the cylinder B3 from spreading wider thanthe lengthof the cylinders.

The shaft of the cylinder B3 is fitted to turn in boxes arranged totraversein slots onthe sides A ofthe frame, and are held up by thesprings B4, and pressed down bythe screws C C, to graduate the thicknessof the dough rolled.

The main cylinder and the cylinder B are connected by gears, one ofwhich is shown at C, to make them turn in unison.

The endless belt or apron C2 passes over the main cylinder, and around`over and under the cylinders G3 and C4, to receive the dough to berolled, which is put upon it between the side-boards G5 CP.

The journals of the cylinder C3 turn in the sides A, and those of thecylinder C4 turn in movable boxes, so that the apron 02 may betightened, as required, by the screws GG.

The cylinder C* is turned by the pulley D3 and band D? to the pulley D5on the shaft Bx ofthe main cylinder.4

The clearing-plate D, for the cylinder B, is pivoted on the sides A atD, and pressed against the cylinder by the springs D2, to scrape ofi'any dough that adheres to the cylinder.

The scraper or separator E is arranged across the apron G2, to separatethe dough from the apron after it is rolled, in order that it may passfreely on to and over the bridge-plate E, which delivers it to theendless aproii of cutters E2, which should move just as fast as theapron O2, so as to receive the rolled sheet of dough to be cut.

The plate E is pivote'd on the stand E3, and its edge is pressed againstthe apron by springs arranged under the plate.

The separator E is fastened to the sides A, as shown in the drawing.

The gear A3 turns the stud-gears F F, one of which turns the shaft L,and the other turns on a stud in the side A, and turns the gear Il1l andshaft F2, which turns in the side A, and has on it two sprocket-wheels,to fit the links of the endless chains F3, which carry the endless apronof cutters E2, which passes around the sprocket-wheels G on the shaft G,which turns in the movable boxes in the side A, adjusted by the screwsG2, to tighten the apron E2.

This apron E2 is composed of bars fastened to the links of the chainsF3, each bar carrying a series of cutters, as shown in fig. 2, whichcutters are open entirely through the bars, so as to allow the lozengesor crackers cut to pass through the apron of cutters, on to the apron orboard arranged under the apron of cutters to receive them.

As the-spaces between the cutters open in passing around the wheels G,the ,pieces or scraps of dough are broken .and loosened, and fall fromthe apron. If any dough should still adhere, it is taken ofi" by th'ecombplate, figs. 3 and 4, which is fastenedto the sides A in such amanner that the teeth project up betweenV the cutters as they pass belowthe Wheel Gr.

To press the dough upon `the cutters and cut it, I arrange the platen Hto traverse vertically on the studs Hx Ain the sides A, and fasten asheet of India rubber or gutta-percha, H2, to the under side of theplaten, to form a iiexible cushion, the platen being held up by thesprings H3 on the studs H1, t0 allow the dough on the cutters' to passunder it. Then, at the proper time, the toothless space Aon the wheel A3allows the apron of cutters to stop, while the cams I-I4 on the shaft A2work the arms I I of the rock-shaft I, and press the platen down uponthe cutters, which cut the lozenges or crackers out of the sheet-dough,and they fall through the cutters upon the endless apron I3, or uponapaper v or board laid upon the apron to receive them.

The rock-shaft I2 is arranged in the studs E3, which are fastened to thesides A, and the arms I have rollers in their ends, for the cams H4 toact against.

The arm Il is connected, by a link, I, to the platen H, which lilik isprovided with a screw, to adjust the platen.

To prevent the apron of cutters from being depressed by the platen whenthe dough is cut, I arrange a clamping-plate, J ,under the lapron 12,011an adjusting-screw in the end of the pronged lever J which 'vibrates onthe ends of the shaft F2, and is 'acted on by the cams H, to raise theplate J and apron I3 up to the under side of the cutters, at the sametime that the platen l presses the dough down into them to cut thecrackers,

and after theyare `cut,'the plate J and apron 1vs drop so low that thecrackers deposited by the cutters upon the carrying-apron -I3 can becarried away without their being disturbed bythe under side of thecutting-apron.

The apron I3 ismounted on the rollers K andK, which turn inthe standsK2, and the shaft of the roller K has the gear L on it, which is turnedby the gear L1 on the shaft L2, which extends across the machine,

land is turned by the stud-gear F, to traverse the apron in motion,audit Will roll the `dough and carry it for- Ward.

The scraper E separating the dough from the apron, it passes over thebridge-plate E, on to the apron E2, and when the sheet of dough hasbeencarried a proper distance under the platen, the rolling andcarrying-devices stop, and the cam H2 Works the platen andclamping-plate, so as to cut the lozvenges or crackers, and then therollingand lcarrying-apparatus proceeds as before. Y l

.1. I claim arranging the cutters in an endless apron', E2, soconstructed as to deliver the lozenges or crackers eut through thecutters, substantially as described.

2. In combination with the rlling and'Y cutting-devices, I claim thebridge-plateA E2, for conducting the sheet of dough from the' apron G2tcthe apron of cutters E2, substantially as described.

3. YIn combination with vthe apron of cutters E2, I claim the platen Hand clamping-plate J, arranged and ,operated substantially as described.l

4. In combinationwith the rolling and cutting-apparatus described, Iclaim the carrying-gear A3,`pro vided' with toothless spaces A4,substantially as and for the purpose set forth.

5. I elaim'the combination and arrangement ,of the arms I and Il,rock-shaft I2, cams H4, and lever l', for the purpose of operating theplaten H and clampingplate J, substantially as described.

6. In combination with the cuttingapparatus, I claim giving to thecarrying-belt I3 an intermitting motion, so that it stops while thecrackers or lozenges arecut, substantially as described.

'7. I also claim the scraper E, across the belt O2, for the purpose ofseparating the dough from the belt, to prepare it to enter thecutting-apparatus.
